dc.description.abstractThis paper reports the first measurement of the effective B0 s → J /ψK0 S lifetime and an updated mea- surement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ eff J /ψK0 S = 1.75 ± 0.12 (stat) ± 0.07 (syst) ps and B(B0 s → J /ψK0 S ) = (1.97 ± 0.23) × 10−5. For the latter measurement, the uncertainty includes both statistical and systematic sources.
